FAQ - Frequently Asked Questions

How long does it take?

Every project we do is unique so there is no one answer. Variables like the size of an object, resolution required, location, and downstream processes like animation or fabrication greatly effect schedule. Most 3D scanning projects that result in us delivering "data only" can be turned around in a few days when the object is shipped to our facility. Once data is complete, small rapid prototypes can be turned around in as little as one more day. Large complex projects sometimes require months. In every case, we can give you clear understanding of the time required once we have your quote request.

How much does it cost?

Here are some terms that you may not be familiar with that appear on our site. From the explanations, you should have a better understanding about the work we do, the services we offer, and the type of equipment we use. If you have any further questions, please contact us.

As-built - a model which captures the exact physical shape of an object.

ASCII (or ASC) - a point cloud file in text format.

CAD - Computer Aided Design

CAI - Computer Aided Inspection

CAM - Computer Aided Manufacturing

CAM2 - Computer Aided Manufacturing Measurement

CMM - Coordinate Measuring Machine

Color Map - a graphical technique to visualize differences between the measured configuration of an object and its CAD model; dimensional differences are mapped onto the CAD model using a color spectrum to indicate location and magnitude. A reference key maps the deviations to values.

Coordinate System - an origin or reference point in 3D (XYZ) space for locating or orienting an object or CAD model.

Decimation - the process of reducing the size of a polygonal model file by decreasing triangle density, resolution, and quantity.

Design Intent - the intended design of an as-built object. Every manufactured part or object varies from its original intended design by some factor. Imperfections can be identified, analyzed, and corrected in reverse engineered models.

Digital Modeling - the process of creating a computer model of an object that exactly replicates the form of the object.

Digitize - the use of a 3D measurement system to capture features of an object. Typically digitizing is used for feature-based measurement of geometry and capturing contours using section cut techniques (as opposed to dense laser scanning).

Direct 3Dview (D3Dv) - a file format, provided by DDI, that offers anyone the ability to view full 3D interactive environments and objects, directly on the web, or in stand-alone format.

Dumb Solid - a solid body in a CAD model that cannot be modified.

DXF - Drawing Interchange File - a line file which can be used to create a 3D model (native AutoCAD format).

Laser Scanning - Laser Scanning is the process of shining a structured laser line over the surface of an object in order to collect 3-dimensional data. The surface data is captured by a camera sensor mounted in the laser scanner which records accurate dense 3D points in space.

Line-of-Sight - the extent to which a laser scanner or other measurement device can capture 3D data from its vantage point. Only points which can be "seen" by the laser will be captured.
